Velbus Ceiling motion and twilight sensor


The VMBPIRC is much more than a motion detector for indoor use. You can simultaneously use motion, twilight and absence detection. The built-in astronomical clock allows the VMBPIRC to operate time-dependently. And on top of that, the module also detects motion for a passage signal or light dependent movement for lighting control.
